a friend of me diving with an Oceanic OCS recently started using subsurface to log her dives.
Unfortunately, it seems like the atom2 parser doesn't support tank switch events on Oceanic OCS yet.
We dumped all dives using the "universal test application". . In the xml sample at the time of the gas switch (at 21:45), there are two <vendor></vendor> elements generated, one starting with "AA", which looks like the gas switch event. The switch was done from air to EAN 52 (the 2nd mix):
<sample>
<time>21:45</time> <vendor type="5" size="8">AA0221296A033400</vendor> <vendor type="5" size="8">024E74039B000001</vendor> <temperature>25.56</temperature> <depth>16.84</depth></sample>
I attached the XML of this dive (sample from 21:45 starts at line 540) and the memory dump.
What about the "34" at the end meaning 52% oxygen in the newly switched gas? Do you have other samples to verify that this theory or should I ask about some more dives with gaschanges to mixes with other amounts of oxygen?
The 0xAA sample indicates a tank switch (for models with support for multiple tank pressure sensors). But it's certainly possible that it can also contain a gas switch. Gas switches are indeed not parsed yet for the Oceanic devices. Is the OCS an air integrated model (hosed or wireless), because in that case a tank switch sample doesn't make much sense.
Can you provide a full memory dump (together with the logfile), rather just one dive. That's a bit easier to work with.
I think I do have some other data from an OCS, but I have no idea whether there are any gas changes or not. I'm a bit in a hurry right now, but I'll have a look later at what data I have available.
